I think the pressure got to Hagler against Leonard

[Master]

Speed, Movement and Fast-Hands really bothered Marvin Hagler.

See his 1st-Bout with Willie 'The Worm' Monroe, who gave Marvin an 'old fashioned'
ass-whipping in Philadelphia.

Damn near won every Round, and had Marvin talking to himself.

What do you think of his fight with Bennie Brisco. I was shocked to see Haglar back peddling & moving. Something very rare.

Hagler was a boxer when he was younger and maybe Briscoe was intimidating so Marvin out boxed him instead.
